Description
Background: In asthma, airway epithelium remodeling can already be detected during childhood, and epithelial cells are more susceptible to virus and oxidative stress. Their exact role in natural history and severity of children allergic respiratory disease remains however surprisingly unexplored.

Description
Molecular mechanisms associated with pathophysiological variations in adipose tissue (AT) are not fully recognized. The main aim of this study was to identify novel candidate genes and miRNAs that may contribute to the pathophysiology of hyperplastic AT. Therefore, wide gene and microRNA (miRNA) expression patterns were assessed in subcutaneous AT of 16 morbidly obese women before and after surgery-induced weight loss. Validation of microarray data was performed by quantitative real-time PCR both longitudinally (n=25 paired samples) and cross-sectionally (25 obese vs. 26 age-matched lean women). Analyses in macrophages and differentiated human adipocytes were also performed to try to comprehend the associations found in AT. 5,018 different probe sets identified significant variations in gene expression after treatment (adjusted p-value<0.05). A set of 16 miRNAs also showed significant modifications. Functional analysis revealed changes in genes and miRNAs associated with cell cycle, development and proliferation, lipid metabolism, and the inflammatory response. Canonical affected pathways included TREM1, PI3K, and EIF2 signaling, hepatic stellate cell activation, and mitochondrial function. Increased expression of SLC27A2, ELOVL6, FASN, GYS2, LGALS12, PKP2, ACLY, and miR-575, as well as decreased FOS, EGFL6, PRG4, AQP9, DUSP1, RGS1, EGR1, SPP1, LYZ, miR-130b, miR-221, and miR-155, were further validated. The clustering of similar expression patterns for gene products with related functions revealed molecular footprints, some of them described for the first time, which elucidate changes in biological processes after the surgery-induced weight loss.

Illumina HiSeq 2500
Description
We report a pilot investigation for poly-A RNAs differentially expressed during Mycobacterium tuberculosis infection. Participation in this investigation from March 2010 to July 2013 was voluntary, only subjects that were >18 years old and that informed written consent were considered eligible. The recruitment of tuberculosis (TB) patients was done at public hospitals in Rio de Janeiro, Brazil. The diagnostic criteria for active pulmonary tuberculosis was at least one AFB (acid-fast bacilli) -positive sputum sample for M. tuberculosis and/or positive sputum culture and/or compatible clinical evolution for pulmonary TB and less than 15 days of anti-TB treatment and was in accordance with those of the Brazilian Ministry of Health. Blood was collected from recent close contacts (rCt) and active tuberculosis (TB) index cases (n=6). Latent TB infection (LTBI) was accessed by both tuberculin skin test (TST, cut-off = 5mm) and in house interferon-gamma release assays (IGRA, cut-off = 100 pg/ml), therefore, 12 rCt were classified as uninfected controls and 16 with LTBI. Subsequently, the sequencing was performed following the standard protocols on Illumina HiSeq® 2500 Sequencing System (Illumina, San Diego, CA) running 100 bp paired-end reads (PE100) and generating approximately 30 million reads passing filter for each sample to produce the mRNA reads. Mining these RNAseq data, highly prominent modulation of DOCK9, EPHA4, and NPC2 mRNA expression was observed in the TB samples, indicating that they might have a role in TB pathogenesis. These differential modulations upon M. Tuberculosis infection were further validated by additional evidences in larger cohorts from different geographical areas. Overall design: We collected blood samples from the recent close contacts (rCt) at the recruitment and monitored them for 1-year. All TB participants were treatment-naïve. An infection mRNA signature was derived from whole blood RNA sequencing data by comparing TB and uninfected rCt. We selected the 3 most prominent genes, by area under the ROC curve analysis, for additional validations. Some of the LTBI participants also showed the mRNA infection profile.
